Hey, looks like there are just 4 different boast, with the same boats in train and test sets. Will there be an additional test set with different boats, or we should just overfit to the 4 boats we have?

Hi @lopuhin, the goal of the challenge is to create models which will be useful in new contexts beyond the data available currently. As always, best practices are encouraged to ensure a model will generalize, and assumptions should be documented for the organizations who will use the models. There will not be a release of additional data during the competition.
